Few ROHM PMICs allow setting the voltage states for different system states
like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific
mechanisms. bd718x7 driver implemented device-tree parsing functions for
these state specific voltages. The parsing functions can be re-used by
other ROHM chip drivers like bd71828. Split the generic functions from
bd718x7-regulator.c to rohm-regulator.c and export them for other modules
to use.

BD71828GW is a single-chip power management IC for battery-powered portable
devices. The IC integrates 7 buck converters, 7 LDOs, and a 1500 mA
single-cell linear charger. Also included is a Coulomb counter, a real-time
clock (RTC), 3 GPO/regulator control pins, HALL input and a 32.768 kHz
clock gate.
Add MFD core driver providing interrupt controller facilities and i2c
access to sub device drivers.

Thanks to Stephen Boyd I today learned we can use platform_device_id
to do device and module matching for MFD sub-devices!
Do device matching using the platform_device_id instead of using
explicit module_aliases to load modules and custom parent-data field
to do module loading and sub-device matching.

Split the bd718x7.h to ROHM common and bd718x7 specific parts
so that we do not need to add same things in every new ROHM
PMIC header. Please note that this change requires changes also
in bd718x7 sub-device drivers for regulators and clk.
